Import invoicing

A user is in a difficult situation regarding import invoicing where a foreign supplier failed to include a consignment in a consolidated invoice and Bill of Lading. This omission was not reflected in the export declaration and the importer only discovered the issue after customs clearance. The user is seeking advice on how the exporter can claim the outstanding amount from the Indian importer, given the lack of evidence and Bill of Entry, suspecting a potential misdeclaration in both countries.
